Performance of Hybrid Batch Training on XTREME-R vs BEIR for Zero-Shot Cross-Lingual Retrieval

Information retrieval across different languages is an increasingly important challenge in natural language processing. Recent approaches based on multilingual pre-trained language models have achieved remarkable success, yet they often optimize for either monolingual, cross-lingual, or multilingual retrieval performance at the expense of others. This paper proposes a novel hybrid batch training strategy to simultaneously improve zero-shot retrieval performance across monolingual, cross-lingual, and multilingual settings while mitigating language bias. The approach fine-tunes multilingual lang

Research goal: Does the hybrid batch training strategy maintain its performance advantages when evaluated using the new XTREME-R benchmark compared to BEIR, particularly for typologically diverse language pairs in zero-shot cross-lingual retrieval?
